' 2 Claims. (Cl. zszzss) This invention relates to new and useful improvements and structural refinements in securing devices for doors, and the principal .object of the invention is to provide a device of the character herein described, such as maybe conveniently and effectively employed in substitution for, or in addition to a conventional door lock, for-firmly and securely retaining the door in its closed position.

In particular, the invention concerns itself with devices employing vwhat may be called ,a pressure exerting member engageable. with the marginal edge portion of-the door, a locking bolt slidable in the member and provided with an extension receivable in the usual latch recess of the door frame, together with actuating means in the form of a nut on the locking bolt whereby the pressure exerting member may be clamped against the door for the'purpose of preventing opening of the latter.

An important feature of the invention resides in the specific structural arrangement of vthe pressure exerting member and lockingbolt, together with means on the member for preventing of, rotation or other displacement thereof, while another feature of the invention resides in the provision of means for retaining the pressure exerting member and locking bolt in a predetermined relative position, so that the entire device may be conveniently and easily applied to the door and frame.

Some of the advantages of the invention lie in its simplicity of construction, in its durability, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the construction and arrangement of parts as shown in the accompanying drawings in which;

Figure 1 is a perspective view of the invention;

Figure 2 is a cross-sectional view showing a door, a door frame and the invention as being applied to the latter;

Figure 3 is a cross-sectional view, similar to that shown in Figure 2, but with the invention installed and the door secured; and

Figure 4 is a longitudinal cross-sectional View of the invention.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

2 a r Referring now to the accompanying drawing in detail, the reference character I0 designates a conventional door provided with a lock mechanism. [2, which includes a projectable. and retractable latch (not shown) receivable in a suitable recess l4 provided in the door frame IS.

The invention consists of a door securing device designated generally by the reference character I8, this embodying in its construction an elongated pressure exerting member 20, which is formed with what will be hereinafter referred to as aflat inner end surface 22, at oneend, and a flat outer .end surface 24 at the opposite end, as will be clearly apparent.

Moreover, the member 20 is provided with alongitudinally extending, circular bore 26, to slidably and rotatably receive a screw-threaded looking post 28, one end of the latter being formed integrally with a flat strip-like extension 30 terminating in an angulated detent 32. 0n the other hand, the relatively opposite end of the bolt 28 is provided with an integral handle 34, this preferably having a U-shaped or a J-shaped configuration, as shown.

A securing nut 36 is freely rotatable on that portion of the handle 34 immediately adjacent the bolt 23, this nut being operatively engageable with the screw-threaded bolt itself, and also being engageable with the outer end surface 24 of the member 20. Finally, it is to be noted that a pair of tapered prongs 38 are provided on the flat inner surface 22 of the member 20, above and below the bolt 28, as shown.

When the invention is placed in use, the free end portion of the handle 34 is engaged with the keeper notch 40 provided on the member 20, this being achieved by first sliding the bolt 28 outwardly in the bore 26 and rotating the bolt so that the handle 34 is alined with the notch, whereupon the bolt is slid inwardly in the bore 26 so that the free end portion of the handle is received in the notch 40, as illustrated in Figures 2 and 4.

By virtue of this arrangement relative rotation of the bolt 28 and member 20 will be prevented, so that the device may be conveniently handled while the detent 32 of the bolt extension 30 is placed in the latch recess 14 of the door frame [6, while the door is partially open, as shown in Figure 2.

The door I!) may then be closed, it being understood that sufficient space exists between the door and the frame to accommodate the extension 30, after which the member 20 may be slid along the bolt 28 toward the door and may be rotated on the bolt through approximately 180, to a position illustrated in Figures 1 and 3. The nut 36 may then be engaged with the screwthreaded bolt 28, and it will be found that by tightening the nut, the flat inner surface 22 of the member 20 will be urged in engagement with the marginal edge portion of the door, so that opening of the door will be effectively prevented.

As the member 20 is caused to exert pressure on the door lfl'bytightening; the nut 36; the prongs 38' will be forced into the space between the door and the door frame, whereby the member 20 will be prevented from rotating or other= wise becoming displaced during the final stages? of tightening of the nut 38.

It is believed that the advantages and-use of the invention will be clearly apparentrfrom-the;

foregoing disclosure, and accordingly, further description thereof at this time is deemed unnecessary.
